action methods returning null, lateron nullpointer

[victor]

Hi,

After upgrading to primefaces 2.2.M1 i see nullpointer exceptions in the following situation:

After a commandLink action method returning NULL (so the same page will be shown again) the page will render correct without errors.

Sample backing bean method:

public String edit() {
editMode = true;
return null;
}


But the next request will give the following error in my logfile:

I am using Glassfish 3.0.1. There are no primefaces component in the page. Only primefaces related showing up in the generated html is.

<link type="text/css" rel="stylesheet" href="/myapp/javax.faces.resource/skins/sam/skin.css.xhtml?ln=primefaces" />

I am suspecting a primefaces filter or something like that.

Regards,
Victor

same issue i experience on 2.2 but goes away when I go back to 2.1 have no idea why this
is not a bigger issue , also found that some resolved by putting a redirect in faces config
navigation case but that did not help me

hopefully this has been identified and will fixed on 2.3 release

[callahan]

grenadadoc fixed what looks like a very similar exception by installing Mojarra 2.0.3. See: http://primefaces.prime.com.tr/forum/vi ... f=3&t=5196. Using PrimeFaces-2.2.RC1-SNAPSHOT rather that 2.2.M1 might be a better idea too.

installing mojarra 2.0.3 on my glassfish (= replacing the jsf-api.jar and jsf-impl.jar ) fixed my issue. Thanks callahan!

I used the mojarra-2.0.3-FCS-binary.zip (Thursday, July 1, 2010 at 9:31:06 PM ) from https://javaserverfaces.dev.java.net/se ... erID=12294

did not work for me and I am not using glassfish using tomcat
